ject of the invention, being the provision of a device by means of which rivets may be fedoneat a time from a magazine to the female member of a manually controlled or mechanically operated riveting machine, the riveting machine being especially adapted for operating upon the headed tubular rivet generally employed in connection with harness. V

A. further object of the present invention, is the provision of a rivet feeding mechanism, in which a manually operated mechanism receives and carries a rivet to the female member of the riveting machine, operating means atthe mouthof the magazine to permit the next succeeding rivet to be fed by gravity to the lower end of the magazine, there being provided further means actuated upon the return of the rivetcarrying mechanism to release such rivet to fall in the latter mechanism so that the next succeeding rivet may be properly delivered.

With the foregoingand other objects in view which will appear as thedescription proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and .claimed, fit. being understood that changes in the precise embodiment of the invention herein disclosed can be made withinthe scope of what is claimed without departing from the spirit of the invention.

trating the coaction of the same with the 7 female member of the rivet machine.

Referring tothe drawings, the numeral 1 deslgnates the base, which has mounted thereon the standard 2 which carries the tubular member '3, the rivet magazine 4 being mounted therein and held in place by means of the screw 5. The magazine4 is disposed in a vertical position so that the ity.

4 below the sleeve 3 are the two transverse slots 6 and 7, each of which has disposed thereln its respective rivet retaining and Provided in the lower end of the magazine rivets R maybe fed therethrough by gravfeeding blade or members 8 andv9, the same being disposed so as to permit of the proper feedingv of the rivets R downwardly and through the outlet end of the magazine 4;.

release the lowermost rivet for delivery into the recess or-receptacle l8 ofthe swinging arm 16, whilexthe blade 9 maintains the next succeeding rivet to permit the same to fall- 'These stops Sand 9 are disposed to engage to be engaged and held by the. blade '8,

when the arm .16 isinitially moved to deliver a rivet. .The two blades 8 and 9 are both carried by and movable with the arm' or supportllO, which arm-or support 10 is mounted for limited or oscillatory move- ,ment upon the upper end ofthevertical post or rod l l..,-'Thus,-theblades have a slight movement in the respectiveslots 6 and7, so ,5 I

that one blade at a time is projected into the path ofthe rivet R; Attached to and" depending from the sleeve 3-;in the path to engage one side of the free end of the'arm 10 is a flat spring plate 12 which norma'llyexerts a tension upon thefreeaend ofthe arm 10to cause the blade 8' to be disposedwithin the magazine 4 and below thev loweremost rivet R, this being the position of theparts when the elements are in dotted line p0sition as shown in Fig. 2. A second resilientplate 13 iscarried by the arm 10 and has its freeend disposed in the path of to be" engaged by-the arm 16 which is carried by the'sleeve and mounted for oscillation uponthelower portion of the shaft 11 and for movement independent of the arm 10.

Thus when the arm 16 is in the full line position as shown in Figs. 2 and 3, the lower end of the. plate is engaged so that the that the lowermostrivet'which was released by the blade 8 was delivered to theoutlet end of the magazine 41 while the rivet thereabout was engaged by the blade 9 and thus consequently-held in this position until the arm 16 was caused to be manually operated to assumethe dotted lineposition as shown in FigzQJ The handle 15 is connected to the sleevelt, so that the carrying arm 15 may be operated in onedire'etion manually.

Carried lathefree end of the arm 16 upbnthe under side thereof by means of the bo1t'17 is-the rivet releasing plate or member 18, which constitutes a movable bottom for the-rivetreceptacle 18", to be operated as will presently appear. One edge of the same, as shown in Fig. 5,is recessed as at 19 while theopposite end is tapered, the purposeof which will presently appear.

Conneeted'to the sleeve 14: in the position opposite-to the handle 15 near the lower end thereof, is'a pin 0r stud 20, upon which'is slidablymounted" one end of the coiled fastened to the base.

spring- 21, the opposite end being connected by means ofthe'fastening device 22t0 one free-end of the 'doublelever 23, said lever 23 being pivoted at 24: and having connected to its'other end, a coiled spring 25, whose opp'osite terminal is connected to the stud 26 Thus when the handle 15 'is'operated'manually'to place the parts inthe position asshown in dotted lines in Fig." 2, the "two springs-will be placedunder tension, so that when the handle 15 is released" after having properly positioned the rivets carried in the free end of the arm16, the springs" will operate to return the member 16 to the position as shown in fulllines, so that the'arm or lever'16 will engage the plate- 13' and'consequently impart movement tothe arm10 so that the blade 8 will'release the lowermost'rivet to fall within the receptacle 18and the blade 9 will be moved across and into the magazineb'elow the next succeeding rivet;

With the presentfmech'anism, the riveting machine 2-7 isemployed the same being provided with the resiliently supported female member 28,which is disposed to coeperate with the male member 30 operated by the coactionof itshead 31 with the cam lever 32. The female die. 28 of the rivet machine is disposed to engage the outer terminal of the rivet releasing member 18' when the same is moved to the dotted line position in Fig. 2, so that the member 18'is'swung on its pivot 17 to permit therivet carried within the receptacle 18lto bedeposited within the female di'e 28headdownward; When the member 18 is moved to releasing position, the recess 19 is below the receptacle, thus rendering it necessary to move the member a shorter distance to release the rivet than would be the case if the full width of the member 18 was employed. It will thus be seen with this mechanism, that as'the member 16 is moved from the full to the dotted line position in Fig. 2, that the arm 10 will be released to it's'spring 19 and the blade 9 will bemoved to release the next succeeding rivet so that the same will fall upon and be engaged by the blade 8, which was simultaneously placed across the magazine-to receive'the released rivet. While the member 16 is moved to deliver, as before described, the rivet in the recess or socket 18 is'delivered to the female riveting member 28. Upon'the release of the handle 15, the spring actuated lever 23 will return the parts to the full line position in Fig. 2, the member 18 engaging the projection 52 of the standard 2 and being moved to close the receptacle 18, while the member 16 engages the plate'13,' which transmits motion to the member 10 so "asto move the blade 8 outwardly to release the rivet held thereby and tomove the blade 9 to engage and hold the next succeeding rivet, such released'rivet falling within the recess 18 of the member 16. The tension of the springs25 and 21 holds the parts in this-position with-the'blade 9 under thelowerm'ost rivet. Thus the arm 10 controls the blades 8 and 9; and consequently the feed'and deliveryof one rivet at a time. It willthus beseen that with a mechanism of this character, that the rivets are delivered in the proper position to the female member of the riveting'machine and that the delivering arm '16 'due to the spring return thereof rapidly returns to rivet receiving positionand outof theway of the rivet setting plunger 30'.
